Value Collection 534284BR Flat Socket Cap Screw M20x2.5

Product Description

The VALUE COLLECTION 534284BR is a metric flat socket cap screw built to DIN 7991 specifications. It features a 90-degree flat head with a hex socket drive and is manufactured from grade 12.9 alloy steel with a black oxide finish. Grade 12.9 denotes an exceptionally high tensile class, making this fastener suited for demanding mechanical and structural assemblies where a flush or countersunk head profile is required. The black oxide coating provides mild corrosion resistance and reduces light reflection. This screw is installed by machinists, millwrights, equipment assemblers, and maintenance technicians working on precision mechanical systems.

This fastener is used in applications requiring a countersunk, flush-mount fastening point in metal assemblies. The M20x2.5 thread size and 35 mm overall length position it for medium-to-heavy structural joints, machinery frames, jigs, fixtures, and industrial equipment where high clamping force and a low-profile head are both necessary. The fully threaded shank maximizes thread engagement across the full grip length. Minimum order quantity is 10 pieces.

Key Features

• Grade 12.9 alloy steel construction for high tensile strength in demanding assemblies
• 90-degree flat head profile allows flush or countersunk installation
• Hex socket drive for high-torque installation with standard Allen or socket tooling
• Black oxide finish provides mild corrosion resistance and a non-reflective surface
• Fully threaded shank maximizes thread engagement
• Conforms to DIN 7991 fastener standard

Compatibility

Designed as a metric-standard flat socket cap screw conforming to DIN 7991, suitable for use in general industrial, mechanical, and structural applications requiring an M20x2.5 thread and countersunk head fastener.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a properly sized hex key or socket driver rated for high-torque applications. De-energize and lock out all equipment before fastener service per applicable safety procedures. Ensure the mating countersink angle matches the 90-degree head profile to achieve full head seating and proper clamp load. Do not substitute with a lower-grade fastener in applications engineered for grade 12.9 hardware.
